AMD Ryzen 9 3900XT vs Intel 10th Gen Intel Core i9-10900KF: Comparison
AMD Ryzen 9 3900XT vs Intel 10th Gen Intel Core i9-10900KF: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: AMD Ryzen 9 3900XT 64 MB against Intel 10th Gen Intel Core i9-10900KF 20 MB, 69% in favour of AMD Ryzen 9 3900XT. Add l2 cache to that, 6 MB on the AMD Ryzen 9 3900XT versus 2.5 MB on the Intel 10th Gen Intel Core i9-10900KF, and the pattern holds. Tdp is not the same on both, 105 W on the AMD Ryzen 9 3900XT versus 125 W on the Intel 10th Gen Intel Core i9-10900KF. Socket is not the same on both, AM4 on the AMD Ryzen 9 3900XT versus FCLGA1200 on the Intel 10th Gen Intel Core i9-10900KF.
Who each one is for
Buy the AMD Ryzen 9 3900XT for mainstream desktop builds and everyday productivity, though it is the wrong buy for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads. Take the Intel 10th Gen Intel Core i9-10900KF for enthusiast desktop builds with a discrete GPU already planned wanting Intel's Comet Lake flagship at a lower price. It is not the one for buyers wanting a fallback integrated GPU, the standard i9-10900K includes UHD 630.
What AMD Ryzen 9 3900XT and Intel 10th Gen Intel Core i9-10900KF have in common
Where they agree, they agree completely, efficiency cores, integrated graphics, socket status, release year and market segment included, so the decision does not turn on any of those. They match on 5 further specifications as well.
AMD Ryzen 9 3900XT vs Intel 10th Gen Intel Core i9-10900KF price
Cost splits them too. Intel 10th Gen Intel Core i9-10900KF sits at $472, AMD Ryzen 9 3900XT at $499, 6% more.
